Some middle-aged and elderly people, especially those with cerebrovascular disease, have been going to various hospitals in winter and spring or during the alternation of autumn and winter seasons to request the input of fluids with blood-stasis activating drugs to prevent cerebrovascular attacks. This phenomenon is common in small and medium-sized hospitals or primary medical offices. Common cerebrovascular diseases can be broadly divided into ischemic stroke (cerebral infarction) and hemorrhagic stroke (cerebral hemorrhage). The common risk factors for cerebrovascular disease are hypertension, diabetes, obesity and hyperlipidemia, smoking and alcoholism, and heart disease. The main drugs for stroke prevention by infusion are thromboxane, hemosiderin, geranium, danshen, shuxin, safflower and other herbal injections. In fact, they cannot effectively prevent stroke, and the infusion itself can increase the chance of infection and infusion reaction. During the infusion process, the drug entering the blood vessels may cause endothelial damage, and the damage may lead to fat deposition, atherosclerosis and the formation of new infarcts over time. A reasonable clinical medication principle should be: no injectable medication if it can be given orally, and as little infusion as possible if it can be given. Although the change of seasons is the high incidence of cerebrovascular disease, there is no scientific basis for relying solely on such preventive infusions to prevent cerebrovascular disease. Cerebrovascular disease should be prevented and treated according to the cause of the disease, and one or two drugs alone cannot play a preventive role. The basic measures to prevent stroke are: improvement of lifestyle and risk factor control, the former includes: reasonable diet, quit smoking and drinking, proper exercise, and balance of mind; the latter includes: regular physical examination, timely adjustment of abnormal indicators, such as control of stable blood pressure, blood sugar, lipid reduction, weight loss, etc.
